Special Issue Information

Dear Colleagues,

Neural-based AI, often referred to as deep learning, leverages artificial neural networks (ANNs) to model complex patterns in data. These networks, inspired by the human brain's structure, consist of interconnected neurons that process inputs and learn from vast amounts of data. Deep learning has revolutionized various fields, including image and speech recognition, natural language processing, and autonomous systems. However, neural networks require extensive data for training and often operate as "black boxes", lacking interpretability and the ability to reason logically.

Symbolic AI, also known as classical AI, relies on the manipulation of symbols and rules to represent knowledge and perform reasoning. This approach excels in domains requiring logical inference, problem-solving, and the use of expert knowledge. Symbolic AI systems can explain their reasoning processes and make decisions based on predefined rules and knowledge bases. However, they struggle with learning from raw data and adapting to new, unforeseen situations, making them less flexible compared to neural networks.

Neuro-symbolic AI aims to integrate the learning capabilities of neural networks with the reasoning and knowledge representation strengths of symbolic AI. This hybrid approach addresses the limitations of both methods by enabling systems to learn from data while also reasoning with structured knowledge. Neuro-symbolic AI can enhance interpretability, allowing AI systems to provide explanations for their decisions and improve their ability to generalize from limited data. Applications of neuro-symbolic AI span various fields, including natural language processing, robotics, cybersecurity, smart cities, education, and various fields of science and technology.

This Special Issue seeks high-quality, original research articles, reviews, and case studies that delve into the innovative use of neural and symbolic artificial intelligence in various aspects of science and technology. Topics of interest include, but are not limited to, the following:

  • Advancements in deep learning techniques for neuro-symbolic integration: exploring innovations in neural network architectures and training algorithms that facilitate the integration of symbolic reasoning capabilities to enhance the synergy between neural and symbolic components.
  • Innovative approaches to knowledge representation in AI: developing new methods for encoding knowledge that can be utilized by both neural and symbolic systems, including techniques for integrating knowledge graphs with neural networks, including large language models (LLMs), to enhance reasoning.
  • Cognitive science perspectives on neuro-symbolic AI: applying insights from cognitive science about how humans integrate perceptual and symbolic information to develop more human-like AI systems.
  • Enhancements in machine learning algorithms through symbolic methods: utilizing symbolic methods to improve machine learning algorithms' accuracy, efficiency, and interpretability, supported by case studies demonstrating the benefits of this hybrid approach in various applications.
  • Case studies and applications of neuro-symbolic AI in science, industry and academia: showcasing detailed case studies of neuro-symbolic AI implementation in real-world scenarios, and analyzing the impact and benefits of these applications in different sectors.
  • The role of formal logic in enhancing AI systems: exploring how formal logic can improve the robustness and reliability of AI systems, and methods for integrating formal logic with neural networks to enhance decision-making processes.
  • Ethical considerations and trustworthiness in neuro-symbolic AI: examining the ethical implications of neuro-symbolic AI systems and strategies for ensuring transparency, fairness, and accountability in these systems (SpringerLink).
  • Future directions and the potential of human-like interaction in AI: exploring future trends and developments in neuro-symbolic AI, and potential applications in creating more natural and intuitive human–AI interactions.

A neural network model for a constitutive law in nonlinear structures is proposed in this paper. The artificial neural network (ANN) model is constructed based on a data set of responses from representative volume elements, which was calculated by finite elements and using an open scientific software machine learning platform. The tangential stiffness matrix, which can be used within a multiscale finite element analysis, is calculated via the method of automatic differentiation. Two types of constitutive neural networks are proposed. The first approach involves training a residual model with three respective surrogate models for the stress components, ensuring less computing cost. The second approach considers a separate ANN for each stress component, ensuring a high rate of convergence. The numerical results are compared with the given data set as well as with the results obtained after applying a polynomial regression. The loss function, without and including the Sobolev metrics, is considered. In addition, a physics-informed constitutive neural model, which enforces hyperelasticity principles, is also analyzed. The choice of the hyperparameters is discussed. Full article

The Internet of Things (IoT) connects people, devices, and processes in multiple ways, resulting in the rapid transformation of several industries. Apart from several positive impacts, the IoT presents various challenges that must be overcome. Considering that related devices are often resource-constrained and are deployed in insecure environments, the proliferation of IoT devices causes several security concerns. Given these vulnerabilities, this paper presents criteria for identifying those features most closely related to such vulnerabilities to help enhance anomaly-based intrusion detection systems (IDSs). This study uses the RT-IoT2022 dataset, sourced from the UCI Machine Learning Repository, which was specifically developed for real-time IoT intrusion detection tasks. Feature selection is performed by combining the concepts of information gain, gain ratio, correlation-based feature selection, Pearson’s correlation analysis, and symmetric uncertainty. This approach offers new insights into the tasks of detecting and mitigating IoT-based threats by analyzing the major correlations between several features of the network and specific types of attacks, such as the relationship between ‘fwd_init_window_size’ and SYN flood attacks. The proposed IDS framework is an accurate framework that can be integrated with real-time applications and provides a robust solution to IoT security threats. These selected features can be applied to machine learning and deep learning classifiers to further enhance detection capabilities in IoT environments. Full article

Computer vision education is increasingly important in modern technology curricula; yet, it often lacks a systematic approach integrating both theoretical concepts and practical applications. This study proposes a staged framework for computer vision education designed to progressively build learners’ competencies across four levels. This study proposes a four-staged framework for computer vision education, progressively introducing concepts from basic image recognition to advanced video analysis. Validity assessments were conducted twice with 25 experts in the field of AI education and curricula. The results indicated high validity of the staged framework. Additionally, a pilot program, applying computer vision to acid–base titration activities, was implemented with 40 upper secondary school students to evaluate the effectiveness of the staged framework. The pilot program showed significant improvements in students’ understanding and interest in both computer vision and scientific inquiry. This research contributes to the AI educational field by offering a structured, adaptable approach to computer vision education, integrating AI, data science, and computational thinking. It provides educators with a structured guide for implementing progressive, hands-on learning experiences in computer vision, while also highlighting areas for future research and improvement in educational methodologies.
